ip 명령을 지속시키는 방법

아이디어 2맞다. 게다가 이 간단한 스크립트를 올바른 파일로 변환하는 것도 어렵지 않습니다. 여기서 한 가지 놀라운 점은 이것이 ip link set mocknet up자동이라는 것입니다. man interfaces좋은 정보를 제공합니다. 작업 문서는 다음과 같습니다.

/etc/network/interfaces.d/mocknet:

# Mocknet: 
#    A mock network meant to replace parts of the real one if they don't exist.
# 
# We are creating a network sink called mocknet. It's a dummy, so data sent to 
# this is ignored. This is useful for when we want to run the simulation without
# all other machines connected. If a machine doesn't exist, then this prevents 
# that packet from being sent to the default route and spamming the LAN.

auto mocknet
iface mocknet inet manual
#
#   This creates the dummy interface.  Dummy means that data sent here will be 
#   ignored.
    pre-up /bin/ip link add mocknet type dummy
#
#   Here we add all of the IP adresses that we might have as host on the FFS.  
#   This guarantees that we can bind to these addresses for Rx and helps us make 
#   a route for Tx
    up /bin/ip addr add 10.10.1.1/24 dev mocknet
    up /bin/ip addr add 10.10.2.1/24 dev mocknet
    up /bin/ip addr add 10.10.3.1/24 dev mocknet
    up /bin/ip addr add 10.10.4.1/24 dev mocknet
    up /bin/ip addr add 10.10.5.1/24 dev mocknet
    up /bin/ip addr add 10.10.6.1/24 dev mocknet
    up /bin/ip addr add 10.10.7.1/24 dev mocknet
    up /bin/ip addr add 10.10.8.1/24 dev mocknet
    up /bin/ip addr add 10.10.9.1/24 dev mocknet
#
#   The previous line created some default routes. Those routes are super high 
#   priority (metric=0) so they override real connections if they exist. We 
#   don't want that so here we need to delete the default routes and then add 
#   good versions. Now if a packet is sent to something in this ip range it goes 
#   to mocknet.  `metric 6000` sets the route priority super low (a bigger 
#   number is lower priority so if it conflicts with a real device, that real 
#   device will take priority and data will be sent and not ignored.

/bin/ip이것이 "올바른" 방법인지 는 확실하지 않지만 모든 것이 작동하는 것 같습니다./sbin/ip
